Gary Larson and the Deacon's pointed head

a) Dalekman61 at the AVPGalaxy forum came up with
an image that's rather worrying in terms of Prometheus' Deacon. The
shape of the head with the back point looks very similar to a Gary
Larson's Alien Family Dinner cartoon featuring the Aliens from
10-5-1986.

b) Gary Larson was an American cartoonist, the creator of The
Far Side, a single-panel cartoon series that was syndicated
internationally to over 900 newspapers for 15 years. The series ended
with Larson's retirement on January 1, 1995
